'WILI;I.AM ERAS'IUS WILLIAMS, OF CHICAGO, ILLINOIS.

lment the hub 1 and the adapter hub 3 in Fig. 5 the tread section is indicated by 8 and becomes a unitary section which is provlded withan internally extendin flange 9 to whichv the disks are attached directly by the rivets 10.

- The tension plate disks are formed of thin sheet metal and are indicated in Fig. 2 by the rear disk 11 and the front disk 12, and their outer ends in Fig. '2 are turned over into a 2 form as indicated by 13-and are thus interlocked between the lower. flange 14 and the main rim portion 4 and the secondary rim portion 7 over as indicated by 15 and reliance is placed upon the rivets 10 for holding the disks in p ace.-

' In Fig.2, however; the margins of the disks are not only held, by the, frictional embrace of the two sections 14 and 7 'ofthe so In Fig. 5, however, the disks areturned rim, but they are further secured by the series of rivets 16.

In the manufacture of these disks I first prepare them as is indicated by Figs. 6, 7, 8 and 9, and the case of the rear disk '11 I emboss a sleeve-like seat-having a corrugated or wavy outline as indicated by 17 while with the-frontdisk this-seat has a smooth outline as indicated by 18.

In both disks I form a series of holes indicated by 19 which areon the lines demarking the aperture to be made in the central portion of the disks where they join into the hub members.

The main sleeve portion of the" demountable hub to'which the disks are permanently secured is indicatedby 20, and a'front view-' of this is shown'in- Fig. 3 and in this view the nose of this hub piece is turned over as indicated by 21 into an'internally extending sleeve-like flange.

From this front end, backward, there are tapering corrugations as indicated by 22 I hub piece 22 I provide a corrugated or fluted ring 24 an edge sectional view of which is.

shown in Fig 14 and a plan. in Fig. 11.

The size and shape of this ring 24: is such that it" forms a press fit when the same is seated in place joining the disk 11 intothe hub member 22 as indicated in Fig. 2.

At the outer end of the hub I provide the hub stamping or nose piece 25 which may be a malleablecasting if desired, but I prefer to make i of a stamping. This nose piece. has its outer end 26 in substantially the same form as the nose of the hub of a wirewheel and this hub piece is also provided with an inclined surface 27 against which the tapered inner nose 28 of the nut 29 clamps, which looks the wheel on to the fixed hub.

From the inclined ring portion 27 of this nose piece there extends. the wall 30 which is turned over into the flange 31 that bears on the seat 18 of the disk 12 and locks the latter tightly into the hub barrel piece 22. After this locking operation is completed there is turned over the flange 33 which permanently secures the nose piece 25 into the hub barrel 22 and thus makes the outer sleeve or hub of the de nountablewheel.

The metal of the disk 11 is turned around over the flange 33 as is indicated by 34, and? thus makes a tight lock ofthe sheet of metal. p

In assemblingthe arts. after the several parts are made and tie disks formed as in.-

-dicated by the 6 to 9 inclusive, I first assemble the disks into the rirnand into the hub barrel 22 as indicated by Fig. 13 and at this stage of the work the disks are firmly secured to the rim.

Then I simultaneously press in the rin 245 and the nose piece 25 from each side an these parts fit against the ortions 35 and 36 of the disks and draw t e metal of the body of the disks into this cavity or seat and in this drawing operation the middle portions 37, as outlinedby the holes 19;, Figs. (Ho 9 are torn loose from the main bodyof the disk and are thus severed and removed and the body of the metal of the disk is drawn tightly into the hub portion, putting tension in the plates all around in the act of assembling the parts.

After the parts are assembled the inner edge of the seat of the front disk. 12 is flanged over as indicated byfia, and the in nor edge of the disk 11 is flattened out into the flange- After this assembly has taken place I weld with a torch a few spots 39 around the edge of the ring 24, which thus binds thisring into permanent relationship in the disk 11., and the hub barrel 22.

Welding is not necessarily employed in making a secure union of the nose piece 25 of the hub into the hub barrel 22, because it is well secured through the medium of the turned flange However, as a matter of safety I weld a few spots 40 on the zone around the front of the disk 12 and the flange member 30 of the nose piece.

- The inner hub 3 of the wheel is provided with a flange 41 which is-turned over into a corrugated flange 42 and the'latter flange is fitted to make a. close union on the inside of the ring 24 and thus. affords the means of preventing the revolution of the hub barrel 22 on the inner hub 3.

The flange 42 is secured by the bolts 43 to the flange 44 of the hub part, which is fixed to the axle but as before described, these two parts. may be made a unitary piece.

Hubs corresponding to thepart'3 are usually made of malleable iron or forgings and made as l have shown, with the flange 41' bent forward and then turned over into the groove 45, which permits. this'flange '42 to be stamped exactly to shape with suitable dies, regardless of whether the material is a'forging or a malleable casting, which is a. desideratum.

It will be readily understood that suitable dies may be made that may finally shape the outer contour of the flange 42 to properly fit the contour; of the ring 24 and thus make a cheap and very desirable means for Zecturing a demountable wheel on to the fixed u In assembling the disks I have shown this Work may be very quickly accomplished and with a certainty of always securingthe desired fit and tension of the parts which is not true in cases where welded sheets or the like are employed.

What I claim isz- The combination with a rim. and a hub barrel of two disks secured to the rimand having their hub zones forced laterally into and closely fitting the interior of the oppo site ends of the hub, respectively, and corresponding clamping rings pressed iitto and permanently fixed in the iii-bent portions of the disks,

2, The combination with a rim and a hub having a barrel, and a nose-piece and clamp- 95 flange 42, leaving the annular corrugated seaeie .tween the interior of the barrel and said nose-piece and clamping ring.

3. In a wheel of the class described, a rim having two disks secured thereto along a common line and the body of the disks diverging from this line to opposite end portions, respectively, of the hub barrel; with clamping members in the ends of the said I hub barrel adapted to clamp the hub region of the disks into the hub barrel and provide the bearing surfaces for the wheel on the inner hub.

i. In a wheel of the class described, a rim composed of two parts, one part having an oii'set annular horizontally extending flange of a diameter smaller than the tread and 'with the secondary part having a tread flange projecting over the said annular flange; with two disks turnedover on their margins and embraced in clamping relation by the two sections of the rim. flange and the parts securedtogether. p

5. In a wheel of the class described, two disks forming the web of the wheel and hav-, ing their outer margins turned over in 2 form and with a rim portion provided with clamping flanges thatembrace the 2 formed edge of the web disks.

6. In a wheel of the class described, having its web portion composed of two disks dished in oppositely disposed relationship to each other and united to the rim along a common line and provided in their hub region with flanges adapted to fit differently inclined portions of the interior of a hub barrel member and means for clamping the said flanges against said interior.

7 In a wheel of the class described, havin its web portion composed of two disks dished in oppositely disposed relationship to each other and united to the rim along approximately the same lines and provided in their hub region with flanges adapted to embrace and engage a hub barrel member and means for clamping thes aid flanges into the hub barrel, said means having bearing surfaces adapted to engage the fixed hub member.

' 8, The combination with a hub having internally sleeve-like slightly tapered end portions, of a rim, two sheet metal disks fixed to the rim and each having a central, cuplike, depressed portion forced into the'corresponding end of the hub to put the body of the disk under tension, and members clamping against the sleeve-like hub the disk parts forced into the latter.

9. In combination, a front disk, a rear disk, a corrugated hub barrel over which fits a lateral, like-corrugated flange of one of the disks, and a like-corrugated clamping ring forcing intimate engagement of the corrugations of the disk and barrel.

10. In a wheel of the class described, having the web formed of disks, a hu barrel embraced by the disks and with the body of the disks turned into the ends of the hub barrel and drawn under tension and securedtherein while the tension is held on the disks.

11. In awheel of the class described, an outer hub and an inner hub, with disks forming'the web of the wheel secured to the outer hub under tension and fixed therein while the tension is held thereon. 12. A. demountale disk wheel composed of a rim, with'two disks forming the web and a demountable hub composed of three pieces, namely a hub barrel, an end piece and a clamping ring and said end piece and clamping ring engaging the metal of the disks and clamping them to the hub barrel.

. 13, In a metal disk wheel, the combination with an inner hub member, of a hub barrel having end pieces furnishing the bearing surface on the inner'hub, and two disks extending outwardly from said end pieces and meeting at the rim.
